CareFusion MicroLoop Manuel D'utilisation page 58

The MicroLoop uses the CareFusion Digital Volume Transducer, an
extremely stable form of volume transducer, which measures
expired air directly at B.T.P.S (Body Temperature and Pressure with
Saturated water vapour) thus avoiding the inaccuracies of
temperature corrections. The transducer is insensitive to the effects
of condensation and temperature and avoids the need for individual
calibration prior to performing a test.
Test results may be uploaded to a PC using Spirometry PC Software
and patient details may be downloaded to the MicroLoop.
